STOP-MOTION FOR QUlLLlNG-ERAMESJ SPECIFICATION forming part of LettersPatent No. 250,949, dated December 13, 1881.

Application filed April 1, 1881.

To all whom it may concern:

Be it known that I, JAMES NEwnY, of Pat: erson, in the county of Passaicand State of New Jersey, have invented a new Improvement in Stop-Motionsfor Quilling-Frames, of

which the following is a full, clear, and exact description. I

The object of my invention is to provide a new and improved device forstopping the rotation of the spindles of quilling-frames, in case thesilk thread that is being wound from the reel upon the bobbin breaks.

In the accompanying drawings, Figure 1 is a cross-sectional elevation ofa quilling-frame provided with my improvement. Fig. 2 is a plan view ofthe cap, the springpawl, and the lever, showing the end of thespring-pawl passed into the recess on the projection of the pulley. Fig.3 is a horizontal sectional elevation of the cap and the projection onwhich it fits, showing the end of the pawl withdrawn from the recess inthe projection. Fig. 4 is a cross-sectional elevation of the cap andtheprojection on which it fits.

A grooved pulley, A, is mounted on a vertical shaft, 0, of the rail B ofthe frame B, and is rotated from the pulley D by means of the belt E.This pulley A is provided with a vertical, cylindrical,orslightly-conical projection, F, having a recess, F, on the side, andover the projection F a cap, G, fits with an aperture, H, in the side,and an outward annular flange, J, at the bottom, this flange resting onthe top of the pulley A. A semicircular rod, K, with a projection orpawl-tooth, L, passing into the aperture H of the cap G at one end, andwith a projection, M, at the other end, is pivoted on the flange J, andis acted upon by a spring, N, which presses the end with the projectionM outward, thereby pressing the end with the tooth L inward-that is,toward the vertical central axis of the cap G. A lever, 0, with agrooved pulley, P, at the outer end, is pivoted to an arm, Q, of therail B, the inner end of this lever O reaching about to the central lineof the cap G. The thread R passes from the reel S over the pulley P,over a pulley, T, on an arm, U, projecting farther from the frame B thanthe pulley P, and through an aperture on the end of averticallyvibrating lever, Z, and to the bobbin V, which (No model.)

rests between the conical rollers W of an arm, X, of the frame B. Thetop of the cap G is provided with an aperture, 1. to receive the lowerend ofa vertical spindle, Y, on which the bobbin V is mounted.

The operation is as follows: As the pulley T projects farther from theframe than the pulley P, and is on about the same horizontal line withit, the tension of the thread R keeps the outer end of the lever Olowered and the inner end raised; but as soon as the thread R breaks,the outer end ofthe lever O is released, causing the inner end to dropupon the flange J of the cap G. As this cap rotates in the direction ofthe arrow at, the projection M of the semicircular rod K will strikeagainst the end of the lever 0, whereby the spring N is pressed againstthe cap G, and the tooth L is withdrawn from the recess F, into which ithas been pressed by the action of the spring N. The lever O prevents thecap G from rotating, and as the pawl-tooth L has beenwithdrawn from therecess F of the projection F of the pulley A, this pulley will rotatewithout rotating the cap G or the spindle Y, and the bobbin V, which isthus stopped as soon as the thread R breaks. This is of great advantage,especially in quilling silk, for if the bobbin rotates when the thread Ris broken, the silk or the bobbin will be burned, or will receive acertain gloss which makes it valueless. As soon as the thread is knottedand passed over the pulley P, the inner end of the lever 0 will beraised, and the cap G, spindle Y, and bobbin V will revolve with thepulley A.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination, with the pulley A, having the vertical projection F,and provided with the recess F, of the cap G, provided with the recessH, spring N, pawl and rod K L, the lever 0, having pulley P at the end,the pulley T, the spindle Y, and mechanism for rotating pulley a, allsubstantially as herein shown and described.
